your problem is about new one Document for all sourcefiles
i think you have 2 solution
1.new document in first step of loop(like below code)
[code]
for (int i = 0; i < sourcefiles.size(); i++) {
for (int j = 0; j <
sourcefiles.elementAt(i).getNumberOfRevisions(); j++) {
Document doc = new Document();
[/code]
2.after iwriter.addDocument, remove all fields in doc
